Generally, salt (which is an inexpensive and stable solution for De-icing) is used to prevent icing the road surface. However, salt has disadvantages which most of them are related to impose heavy costs associated with road pavement and increase the risk of road accidents in the winter.In the meantime, one of the ideal materials for road surface de-icing which can be used as a substitute for salt is calcium magnesium acetate (CMA). In this study, based on a laboratory study and performing British pendulum test in accordance with Standard BS118 for different samples of pavement, including asphalt pavement, typical concrete avement, self-compacting concrete and pavement by aggregate materials, the effect of the use of the calcium magnesium acetate on sliding resistance of road surface in the winter's maintenance road has been investigated, and are compared to the salt.According to the test results on all types of pavement samples, CMA, rather than salt, increases slip resistance. Accordingly, the use of CMA reduces road accidents in winter by increasing the slip resistance of the road surfaces and use it instead of salt in the winter's maintenance road is recommended.
